Date Apr. 20, 1989.When towing large aircraft with a tractor damage may at high speeds inadvertently be done to the nose wheel gears of the aircraft if the pilots of the aircraft apply the brakes. This can be avoided by automatic control whereby the transmitted force is sensed and the power and braking of the tractor is controlled on the basis of said sensing. By tractors of that kind it is difficult to sense the transmitted power directly. Instead, according to the invention, the acceleration of the tractor and the supplied power of the tractor are sensed. On the basis thereof it is possible to calculate the transmitted force and to drive accordingly.

Abstract: Ozone and chlorine are used to bleach cellulosic fibrous material pulp in the production of kraft pulp for paper and paper products, being applied together in a mixture. When the ozone and chlorine are applied simultaneously it is possible to achieve delignification to a greater extent than is possible utilizing chlorine at any level. The total chlorinated ring compounds in the bleach plant effluent are remarkably reduced utilizing the ozone-chlorine mixture, compared to all chlorine, with resulting decrease in the fish toxicity of the bleach plant effluent. Utilizing an O3/Cl2 Eo D bleaching sequence (only three stages) it is possible to obtain pulp with 90 TAPPI Absolute, or greater, brightness.

Abstract: An arrangement for space heaters for motor vehicles, which are fired with liquid fuel including, (depending on the type of burner used), a glow plug for either igniting a fuel/air mixture and/or vaporizing fuel. Only one type of glow plug, i.e., a glow plug designed for a 12-V electrical system, is normally employed. If the motor vehicle has a 24-V battery, a compensating resistor, which has the same electrical resistance as the glow plug, is connected in series with the glow plug. The amount of electrical energy converted into heat in the compensating resistor is practically equal to that transformed in the glow plug. The compensating resistor is integrated within the burner housing, in which case it is located in the flow path of the combustion air and is properly cooled by the air flowing past it, to provide a safe trouble free and space-saving arrangement.

Abstract: PCT No. PCT/SE90/00710 Sec. 371 Date Apr. 22, 1992 Sec. 102(e) Date Apr. 22, 1992 PCT Filed Nov. 2, 1990 PCT Pub. No. WO91/07807 PCT Pub. Date May 30, 1991.A DC/DC power transformer is provided which is an arrangement for direct transformation of high electric power from one DC voltage level to another DC voltage level without an intermediate AC voltage network. The DC voltage is today basically used for transmission of high electric power at long distances. The DC voltage levels for these transmissions are normally high. The DC/DC power transformer allows several DC voltage levels to be used in one and the same DC voltage network. The principle for this arrangement is that the valve windings (43, 45) from one or several converter transformers (47) are connected to two valve bridges, which generate opposing cyclically variating magnetic flows in the transformer cores (44). One of the valve bridges is operated as an inverter (42) and the other as a rectifier (46) and in this manner the power is transformed from one DC voltage level (Ud1) to another (Ud2). At high voltage levels the leakage inductances in the transformers will be high as a consequence of the insulation levels and therefore special arrangements must be made in order to commutate the magnetic energy from one phase of the transformer to another without creating great losses.

Abstract: A method and an apparatus for measuring low energy radiation from a sample provided on a sample carrier (6, 6<I>). The sample is positioned in a shielded cavity (8) between two oppositely aligned Geiger-Müller tubes (11, 12) such that sample radiation either reaches both of the tubes or one of the tubes, in which case the other tube is for measuring background radiation only. Both tubes are used for measuring coincidental pulses, which are disregarded. A background radiation value, to be subtracted for obtaining a sample radiation value, is determined using either a historical background radiation value or both the historical background radiation value and a background radiation value obtained during the actual sample measurement. In the case of both tubes measuring sample radiation, there can be provided a third Geiger-Müller tube (13) for measuring background radiation only.

Due to an absorption of the laser beam by the small smoke particles an increased temperature is obtained on the protective glass plate and the mechanical parts that are attaching the protective glass in its holder (4). As soon as the detector signal has reached a certain level it can be indicated that it is time to replace the protective glass plate. The thermal detector (10) is preferably combined with an optical detector (8) sensing the radiation scattered by larger dirt particles collected on the protective glass plate during the machining process.

Abstract: The present invention provides an apparatus and method for accomplishing fluid disinfection by passing fluid flow through a uniform array of ultraviolet lamps having cross sections perpendicular to the direction of fluid flow that define channels for the fluid flow. Positioned next to the end of each lamp at the entrance of the fluid flow are triangular shaped delta wings having surfaces inclined at an angle to the direction of fluid flow. The interaction of the fluid flow with each delta wing creates a pair of vortices that rotate in the same direction or in directions opposed to each other. The counter-rotating vortices reinforce each other to minimize dissipation of their mixing strength as they move down the channel. Due to these co-reinforcing properties these counter-rotating vortices more promote efficient mixing of the fluid which is required to achieve more efficient use of the light in the UV disinfection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired.
